Raspberry Pi 400

Last updated: 25 October 2026

What the Raspberry Pi 400 is

Raspberry Pi built this keyboard computer around a purpose-made board based on the Raspberry Pi 4. So it has the same 1.8GHz quad-core processor and 4GB of memory, but inside a keyboard. Raspberry Pi says its thermal design keeps it cool and silent, so there is no fan.

The 40-pin GPIO header sits on the back edge. That means you can still wire up lights, sensors and motors for electronics projects.

What it does

• Runs a desktop: Raspberry Pi OS handles web browsing, documents, email and a calendar.
• Teaches coding: Raspberry Pi pitches it at students of all ages, for programming, physical computing and networking.
• Drives two screens: meanwhile, two micro HDMI ports support up to 4K at 60 frames a second.
• Connects to anything nearby: wifi, Bluetooth 5.0 and Gigabit Ethernet are all built in.
• Plugs into projects: the GPIO header takes the same add-ons and wiring as a Raspberry Pi 4.

Key facts

• Price: £57.60 for the unit on Amazon UK, the same as The Pi Hut. The Pi Hut's full kit is £76.80
• Processor: Broadcom BCM2711, quad-core Cortex-A72 at 1.8GHz
• Memory: 4GB LPDDR4
• Ports: 2 x USB 3.0, 1 x USB 2.0, 2 x micro HDMI, Gigabit Ethernet, microSD slot, USB-C power
• Keyboard: 78 or 79 keys, depending on the regional layout
• Size: 286 x 122 x 23mm
• In the kit: mouse, power supply, micro HDMI to HDMI cable, a microSD card with Raspberry Pi OS and the official Beginner's Guide

Who the Raspberry Pi 400 suits

• Children and teenagers learning to code: it plugs into the family TV, and the board sits safely inside the keyboard.
• Teachers and code clubs: at £57.60 a unit, ten for a classroom cost £576.
• Tinkerers who want a tidy desk: the GPIO pins mean it still works for wiring projects, even though it looks like a keyboard.

The limits

First, the unit on Amazon is the keyboard alone. You need a USB-C power supply, a mouse, a micro HDMI cable and a microSD card with an operating system. So if you have none of those, the £76.80 kit from The Pi Hut is the simpler buy.

Its board comes from the Raspberry Pi 4, which launched in 2019. Raspberry Pi's newer keyboard computer, the Raspberry Pi 500, uses the faster Raspberry Pi 5 chip. However, The Pi Hut had it at £172.80, about three times the price.

Also, the computer keeps your files on the microSD card. So buy a card big enough for your files and projects.

Where to buy the Raspberry Pi 400 in the UK

Amazon UK sells the UK-layout unit through CreativeMind Products, and Amazon handles dispatch. The Pi Hut, a UK Raspberry Pi shop, also sells the unit and the kit. The full specification is on the official Raspberry Pi 400 page.

FAQs

How much is the Raspberry Pi 400 in the UK?

£57.60 for the unit on Amazon UK and at The Pi Hut. The Pi Hut's kit, with a mouse, power supply, cable and card, is £76.80.

Does it come with a screen?

No. You plug it into a TV or monitor through micro HDMI, and it can run two screens at once.

What is the difference between the Raspberry Pi 400 and the Raspberry Pi 500?

The 500 is the newer keyboard computer, with the faster Raspberry Pi 5 chip. But it costs about three times as much, so the 400 still suits learners on a budget.

Can I use the Raspberry Pi 400 for electronics projects?

Yes. The 40-pin GPIO header on the back takes the same wiring and add-ons as a Raspberry Pi 4.

Is it good for children?

Raspberry Pi designed it for learners of all ages. Because the board sits inside the keyboard, there are no exposed parts to knock.
